Gallery Module for AsgardCMS

Special Thanks

to Nicolas Widart for AsgardCMS

Installation

You can install Gallery module using composer: composer require bociancz/gallery-module

After the module is installed, you have to give yourself access in AsgardCMS (using Roles/Permissions). New Gallery item will appear in the Sidebar.

Prerequisites

Gallery module by default uses Bootstrap 4 grid system and img-fluid classes to render gallery thumbnmails. If your frontend theme does not use bootstrap, you can load bootstrap CSS from CDN https://getbootstrap.com/docs/3.3/getting-started/ (bootstrap JavaScript is not needed).
Alternatively, you can use your own blade template to render gallery or switch to the Bootstrap 3 template also provided with the library (see Advanced Usage)

Usage (basic)

You can use Gallery module administration to create galleries using photos uploaded through Media module. Each gallery will generate a short code snippet that you can copy and paste either into the blade template, or into any page or article (created for example using Page or Blog module).

Register Middleware

In order for the code snippet to be transformed into gallery HTML code, you need to register RenderGallery middleware to the routes you want gallery module to kick in.

This can be done globally by editing app/Http/Kernel.php file and adding \Modules\Gallery\Http\Middleware\RenderGallery::class into the $middlewareGroups web group (this way, gallery will automatically render in all web routes on frontend):

 
<?php
    // app/Http/Kernel.php
    ...
    protected $middlewareGroups = [
        'web' => [
            ...
            \Modules\Gallery\Http\Middleware\RenderGallery::class,
        ]
    ...
}

Gallery Frontend

Gallery module uses baguetteBox.js library (https://feimosi.github.io/baguetteBox.js/). BaguetteBox.js is a lightweight (3.2kB minified/gzipped) responsive CSS3 gallery with no extra dependencies (i.e. jQuery is not needed)

In order to get full frontend functionality running:

  • include baguetteBox.js JavaScript file into your page. You can simply load files from CDN <script src="https://cdnjs.cloudflare.com/ajax/libs/baguettebox.js/1.9.1/baguetteBox.min.js" async></script>
  • include baguetteBox.js CSS file into your page <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/baguettebox.js/1.9.1/baguetteBox.min.css" />

or you can use local assets provided with the module (see Advanced Usage)

Usage (advanced)

Alternative middleware registration

If you do not like using Gallery middleware globally for the whole website, you can apply gallery.render middleware alias selectively to the specific frontend routes in your application

<?php
    // Modules/YourModule/Http/frontendRoutes.php
    ...
    // middleware will be applied to this specific route
    $router->get('your-url', 'YourController@method')
        ->middleware('gallery.render');
    ...
    // middleware will be applied to whole group
    $router->group(['middleware' => 'gallery.render'], function(Router $router) {
        $router->get('your-url', 'YourController@method');
        ...
    });
    ...
?>

Load frontend assets locally (not from CDN)

if you are not a fan of loading frontend assets from CDN, you can use local copy provided with the Gallery module for convenience:

  • first publish module assets php artisan module:publish Gallery
  • use <link rel="stylesheet" href="{!! Module::asset('gallery:css/baguetteBox.min.css') !!}" /> instead of the CDN CSS
  • use <script src="{!! Module::asset('gallery:js/baguetteBox.min.js') !!}" async></script> instead of the CDN JS

Customize Gallery look

Gallery module has several pre-loaded templates. By default, it will use simple bootstrap-based template with gallery JavaScript plugin baguetteBox.js (no jQuery neded), located in Modules/Gallery/Resources/views/frontend/bootstrap4-baguettebox.blade.php. There are several ways of changing this this default behavior:

Module Settings

you can go into the Gallery module Settings in admin interface, and enter one of the example gallery templates into the "Default Template" field. Current options are plain (simple display of img tags), plain-links (simple image tags, links open to new tab/window) or bootstrap4-baguettebox / bootstrap3-baguettebox (Bootstrap 4 or 3 and BaguetteBox.js based responsive template with lightbox - Bootstrap 4 is also a default option)

Custom single default template

you can create your own gallery template in Theme/YourTheme/view/partials/gallery.blade.php. If Gallery module finds a file in this location, it will automatically use it instead of the default one. Feel free to copy contents of one of the the module-provided samples to get an idea about what the file may look like. There are several examples in the Modules/Gallery/Resources/views/frontend directory

The simplest gallery template example would be something like this:

@foreach($gallery->files as $picture)
    <img src="{{ $picture->path_string }}" />
@endforeach

but you can of course override the file as you like. You have $gallery variable available in the template, which is an instance of Modules\Gallery\Entities\Gallery class.

Custom template in the shortcode

you can also provide your own custom gallery template by manually tweaking the gallery shortcode. Standard simple gallery shortcode looks like this [[GALLERY(gallery_name)]]. It is kind of like a GALLERY() function with a single parameter (gallery_name).

You can also provide a second parameter template_name. If you do, the module will use it instead of the default.

The shortcode will then look like this [[GALLERY(gallery_name,template_name)]], where template_name is name of your template, relative to your active frontend Theme using dot notation.

For example, shortcode [[GALLERY(my-gallery,galery.homepage.lightbox)]] will load gallery named my-gallery, and it will use template located in Themes/{your frontend theme}/gallery/homepage/lightbox.blade.php
